Hi, this header (header.h):
#pragma GCC system_header
int noreturn() { }
included by (file.cc):
#include "header.h"
void ok() { }
Leads to:
paolo:~/Work> g++ -Wall -c file.cc
header.h: In function 'int noreturn()':
header.h:2: warning: control reaches end of non-void function
Note, this problem doesn't happen if file.cc is compiled as C, thus the problem
apparently is the C++ front-end not setting TREE_NO_WARNING on the decl or
something similar...
